GIRT FOR LOOP DRIERS.

Application filed September 2'4, 1925. Serial No. 58,346..

My invention relates to certain improvements in girts used in loop driers. The girts are connected to chains and are spaced a given distance apart, forming a carrier for the material to be dried. These chains have rollers which travel over rails extending longitudinally through the drying chamber, and the material to be dried is festooned over these girts, with means for moving the carrier through the drier.

The object of my invention is to provide means for allowing the cloth, or other material, to freely shrink while festooned on the girts.

A further object of my invention is to provide means for allowing air to freely circulate between the girt and the material.

A still further object is to provide means to prevent the marking of the cloth while being carried on the girts.

In the accompanying drawing:

Fig. 1 is a. transverse sectional view of a drying apparatus, illustrating my improved irt;

g Fig. 2 is an enlarged sectional view on the line 2-42 of Fig. l; and

Fig. 3 is a view illustrating a modification of the invention.

The casing 1 of the drying chamber may be of any suitable type, having rails 2 on which the carrier 3 travels. The carrier has two chains 4 connected by a series of transverse girts 5. The girts are hollow and are flattened at each end, as at 6. These flattened ends are secured to the fittings by bolts or other tastenings.

It has been the usual practice to allow the cloth to be suspended in festoons directly upon the girts. It has been found that, when so i'estooned, the cloth will not shrink as thoroughly when it is in contact with the girt, as it does in other places, neither does the cloth dry as quickly.

In order to overcome this detect, a coiled wire, in the form of a spring, is mounted on each girt, and the ends 8 of the wire are passed through holes in the girt, as clearly shown in Fig. 2. The coil is preferably greater in diameter than the girt, and has a line bearing only on the upper portion of the girt, so that by this construction, the coiled wire is free to move longitudinally on the girt. When the cloth is testooned on the improved girt, it is carried by the convolutions of the wire, so that when the cloth, or other material, shrinks, the coiled wire moves with it.

The wire is flexible enough that it will follow the movement of the shrinking cloth, and as soon as the cloth is shrunk and dried, and removed from the girt, the wire will assume its original position on the girt. In some instances, the coiled wire may be made as shownin Fig. 3, in which the convolutions are spaced further apart at the ends than at the center of the girt. It will be understood that the relative movement of the cloth with respect to the girt, due to shrinkage, will be greater at the edges of the .cloth than at the center.

It will be seen also that the cloth rests upon the convolutions of the coiled wire, and

this allows the air to freely circulate under the cloth, with the exception of those portions directly in contact with the wire. wire is preferably made of brass or bronze, in order to avoid rusting.

I claim:

1. The combination in a testooning drier for shrinking cloth or other material, of a series of girts on which the cloth is festooned; and means on the girt for supporting the cloth, said means being capable of moving with the cloth as it shrinks.

2. The combination of a girt on which cloth is festooned; and a coiled wire mounted on the girt and arranged to support the cloth, said wire being free to move with the cloth as it shrinks.

. 3. The combination of a girt; and a coiled wire mounted on the girt and attached at each end to the, girt, said wire being of greater diameter than the girt and arranged to support the cloth and to move with the cloth as it shrinks.

4. The combination of a girt; and. a coiled wire mounted on the girt, the convolutions of the coil being closer together at the center than at the ends.
